The Scandinavian Defense all lives under one ECO code — B01 — but inside that code Black gets a real choice of personality. Do you recapture with the queen (and pick a square for it), or with the knight? Each road has its own feel. Here’s the map.
The variations at a glance
Variation Key moves Personality Who it favors Main Line (Qa5) 2…Qxd5 3.Nc3 Qa5 Classic, active queen Balanced, solid Modern Qd6 2…Qxd5 3.Nc3 Qd6 Flexible, fashionable Balanced, easy to play Scandinavian Qd8 2…Qxd5 3.Nc3 Qd8 Ultra-solid, modest Slight space edge, White Modern Variation 2…Nf6 Piece play, no queen sortie Dynamic, balanced Icelandic / Gambit lines 2…Nf6 3.c4 e6!? Sharp pawn sacrifice Double-edged
The Main Line: 3…Qa5
After 2…Qxd5 3.Nc3, the classic retreat is 3…Qa5. The queen stays active on the queenside and stays clear of Black’s developing pieces.
Black follows up with the trusty setup: …Nf6, …c6, …Bf5 (or …Bg4), …e6, then castles. The …c6 move is essential — it gives the queen a bolt-hole on c7 and stops White’s Nb5/d5 tricks. It’s solid, principled, and the most-played version of the opening. (See the move-by-move guide for the full walkthrough.)
The Modern Qd6 Variation
The big modern fashion. After 3.Nc3, Black plays 3…Qd6, parking the queen on a square where it’s flexible, defends nicely, and stays out of the c-pawn’s way.

The Qd6 Variation — the queen sits flexibly on d6 while Black completes a harmonious setup.
Why d6? The queen avoids the pin tricks that can hit it on a5, it eyes the kingside, and it supports an eventual …e5 break. Sergei Tiviakov did more than anyone to prove this line is fully sound, scoring an enormous number of games with it. If you want the simplest, most reliable Scandinavian, 3…Qd6 is a fantastic pick.
The 3…Qd8 Variation
The most modest retreat: the queen just goes all the way home.
Yes, Black has spent two whole moves moving the queen out and back. In return, the structure is utterly pristine and Black has a clear plan: …c6, …Nf6, …Bf5/…Bg4, …e6, castle, and slowly catch up. White gets a comfortable space edge for the time spent, but Black is rock-solid and hard to break. It’s a “I’ll take a slightly worse but totally safe game” choice — and at club level that’s often a great deal.
The Modern Variation: 2…Nf6
Don’t want to bring the queen out at all? Then meet 2.exd5 with 2…Nf6, planning to win the pawn back with the knight. After 3.d4 Nxd5, Black gets a clean, piece-driven game.

The Modern Variation — Black recaptures with the knight and often fianchettoes the bishop to g7.
Black typically develops with …g6 and …Bg7 (a fianchetto setup) or …Bf5/…Bg4 and …e6. There’s no early queen sortie, so the tempo issue of the queen lines disappears entirely — at the cost of letting White keep a slightly freer position with the big d4-pawn. It’s a great choice if the early …Qxd5 makes you nervous.
White can also try to hang on to the pawn with 3.c4, gripping d5. That leads to sharper play and to gambit ideas below.
The Icelandic and gambit lines (2…Nf6 3.c4 e6!?)
The spiciest corner of the Scandinavian. If White grabs space with 3.c4, Black can sacrifice a pawn with 3…e6!? — the Icelandic Gambit — ripping the position open for fast development.

The Icelandic Gambit — Black gives up a pawn (after 4.dxe6 Bxe6) for rapid development and open lines.
After 4.dxe6 Bxe6, Black is down a pawn but has all the pieces flying out, open files, and pressure on White’s slightly loosened position. It’s genuinely double-edged — modern engines say White is holding a small edge with accurate play, but over the board it’s a real headache. Only dive in if you enjoy gambits; if not, just recapture on d5 in the main Modern lines instead.
A close cousin is the Portuguese / Elbow-room Gambit, where after 2…Nf6 3.d4 Black pins with 3…Bg4!?, daring White to grab the d5-pawn while Black develops with tempo. Like the Icelandic, it trades a pawn for activity and surprise value — fun at club level, but objectively White is fine with careful play. The honest theme across all the gambit lines is the same: Black gets practical chances and initiative, but no free lunch, so reach for them only if attacking play is your thing.
A quick word on move orders
One reason the Scandinavian is so beginner-friendly: the variations mostly converge on the same harmonious setup regardless of which queen square you pick. Whether the queen goes to a5, d6, or d8, Black almost always wants …Nf6, …c6, the light-squared bishop out to f5 or g4, and …e6, then castles. So choosing a variation is really just choosing where the queen lives — the rest of your development barely changes. That’s a huge practical advantage: you learn one structure and it serves you in every line.
So which variation should you study?
- Want the classic, most-played version? Learn the 3…Qa5 main line.
- Want the easiest, most reliable system? Play 3…Qd6 — one harmonious setup, minimal theory.
- Want maximum solidity and don’t mind being patient? The 3…Qd8 line is bulletproof.
- Hate the early queen move? Go 2…Nf6 (the Modern Variation).
- Love gambits? The Icelandic is your wild card.

FAQ
What is the best Scandinavian Defense variation? There’s no single “best” — the 3…Qa5 main line is the classic, 3…Qd6 is the fashionable modern choice (and very easy to play), and 2…Nf6 avoids the early queen move entirely. All are sound.
Why is 3…Qd6 so popular now? The queen on d6 dodges some of the harassment it faces on a5, stays flexible, and supports an …e5 break. Sergei Tiviakov popularized it with a long, successful run of games.
Is 3…Qd8 too passive? It loses two tempi, so White gets a comfortable space edge — but the structure is flawless and it’s fully playable, especially below master level where solidity goes a long way.
What’s the Modern Variation in the Scandinavian? It’s the 2…Nf6 line, where Black recaptures on d5 with the knight instead of the queen, avoiding the early queen sortie and aiming for active piece play.
